  Hello...
  
  Does the hydrodynamic response module in workbench calculate the second-order mean drift forces for regular waves? If yes, how can I get the data in the time domain?
  
  Thanks.

  No, it does not. The second order mean drift force is included in the time domain irregular wave response with slow drift or slow drift only analysis. The time domain regular wave response incluse the nonlinear incident wave force and hydrostatic force.
